I have to agree with the review titled "Misleading Title." It spends an inordinate amount of time covering America AFTER Columbus. That was disappointing because I was looking forward to learning what the title promised but didn't deliver. As for being political and biased, there's enough of that to go around here. I can't say it was subtle nor tremendously obvious. Nor can I say either way is appreciated. I will agree with those who value the production quality, it is good. But I reiterate that you should not expect it to spend the bulk of its time on America BEFORE Columbus. Disappionting.
